Hi,

There are many colleges in science stream, the most popular among them are-

1. MBBS / BDS / BAMS / BHMS/ BEMS

2. BSc in CHEMISTRY, BOTANY, ZOOLOGY , MICROBIOLOGY, BIOTECHNOLOGY , PHARMACY , PHYSIOTHERAPY, ANTHROPOLOGY , BIOCHEMISTRY and a lot more

3. BE / BTech / B.Arch BSc IT and software ( considering you mentioned science )

Top most colleges for medical are AIIMS, GMCs, GDCs in terms of govt seat. There are also private colleges. But you can only take admission through clearing NEET exam.

Considering the current situation of the pandemic, its quite uncertain as when will the college reopen, but you can keep a check on your desired college through their official website.

Hope this helps.
